The contacts 32, 33, and 34 constitute vertical section on the line 4-4 of Fig. 2. the selector switch. By rotation of the shaft 28,

A casing of the type in which my device is en-- the outer end of the movable contact 33 may be closed may take any desired form, the form brought into engagement with any of the fixed shown in the drawings being that shown in the contacts 32 to predispose the sound reproducing mechanism, by means hereinafter described, for reproduction of any of the available recordings.

To indicate to the operator the title of the recording which the sound reproducing mechanism is predisposed to reproduce, there is mounted upon the shaft 28 a cylindrical drum 36 which carries, arranged in an annular series, the titles of available recordings. As shown in the drawings, the drum 36 is provided with an annular series of axially extending slots 31 and with guides 38 which hold in respective association with the slots 31 cards 39 bearing the titles of available recordings. The cover I is provided in its front wall with a window 40 exposing to view a limited number of the titles on the drum 36; and associated with such window there is an index 4| (Fig. 1) indicating the title of the recording which the sound reproducing mechanism is predisposed to reproduce. As will be clear from Fig. 4, the drum 36 has a closed end 42 provided with a hub 43 which receives the shaft 23 and is rigidly secured thereto as by means of a set screw. The opposite end of the drum 36 is open to permit insertion and withdrawal of the cards 39.

For the purpose of illuminating the titles of available recordings on the circumference of the drum 36, the cards 39 bearing such titles may be of translucent material and the lamp Il may be mounted within the drum in line with the window 40. Conveniently, the lamp I0 is mounted upon a support 1| having in rear of the lamp an extended, polished surface to reflect light through the translucent cards and the window 40.

The mounting of the list of available recordings upon the drum and the direct association of that drum with the selector switch and the index has a distinct advantage. Only a portion of the list of available recordings is visible through the window, and any prospective operator is impelled by curiosity to rotate the drum and discover the titles of the remaining recordings. The direct association of the titlebearing drum with the selector-switch facilitates operation; for, when the selector switch is set to reproduce any recording, the title of that recording appears in line with the index.

I claim as my invention:

1. In a remote control device for a selective sound-reproducing mechanism selectively operable to reproduce any of a number of recordings, a casing, a horizontal shaft extending through said casing and projecting through at least one side wall thereof, a control knob on said shaft for rotating it, a drum secured to said shaft within said casing, said drum bearing an annular series of titles of the available recordings, said casing having in its front wall a window through which a limited number of said titles are visible, and selecting mechanism operated by said shaft for controlling the operation of said selective sound-reproducing mechanism.

2. In a remote control device for a selective sound-reproducing mechanism selectively operable to reproduce any of a number of recordings, a movable control member, a list of the titles of available recordings movable jointly with said control member, a stationary index past which the titles successively progress as the control member is moved, and selecting mechanism operated by said control member for controlling the operation of said selective sound-reproducing mechanism.

3. In a remote control device for a selective sound-reproducing mechanism selectively operable to reproduce any of a number of recordings, a rotatable shaft, a cylindrical drum secured to said shaft and co-axial therewith, said drum bearing an annular series of titles of available recordings, a stationary index past which said titles successively move as said shaft is rotated, and selecting mechanism operated by said shaft for controlling the operation of said selective-sound reproducing mechanism.

4. The invention set forth in claim 3 with the addition of a casing enclosing said drum, said casing being provided with a window through which a limited number of said titles are visible, and said index being associated with said window.

5. The invention set forth in claim 2 with the addition that said control member is rotatable, said list of titles being supported from and rotatable with said control member and being arranged in a circumferentially extending series.

6. The invention set forth in claim 3 with the addition that said titles are removable from.

association with said drum for replacement with a difierent series of titles.
